NL Omaha Hi Lo Poker Cash Games
Beware of NL Omaha Hi/Lo cash games. These games can get very juicy and going all in is very common for players. Be sure you have the bankroll to enter these. I would suggest at least 25 times the amount you buy into the game with. This will allow a couple rebuys if you need to without draining your bankroll. Do not plan on entering these games if you are afraid to put all your chips on the line in one bet.
NL Omaha Hi/Lo
NL Omaha Hi/Lo is more of a "gambling" game compared to PL Omaha Hi/Lo. Play is fast and the pots build up quick. Most of the players there are just trying to double up real quick and leave. You really never know with some plays if the player actually has something or is just trying to buy the pot with the big all in bet.

NL Omaha Hi Lo Tips
Limit your time at these tables. If you get up to over double your stack, I would suggest you leave. It will become to tempting to call some of the all-in bets since you have made some more cash. In the end you have no idea what will flop, so even a really good hand like AA23 could lose to 9 10 J Q. Trying avoiding calling an all-in pre-flop unless someone pushes into you and your holding AA23 doubled suited or similar. The big pots in NL Omaha Hi/Lo come from quartering an opponent. A good all-in bet would be if you have not low and good high as well. You are hoping that the other player calls with the low as well and you winning the high, winning ¾ of the pot.
I recently encountered a very juicy game of $5-$10 NL Omaha Hi/Lo at Full Tilt. This table was completely out of control. Several players were pushing all-in pre-flop with $200-$500. Over 50% of the people all-in had Ace /Two. Most hands were not great by any means. I ended up doubled up real quick when I had AKK3 and just winning the high. Players coming and going as they lost their stack or just doubled up and left.
Remember to wait for your hands because most of the players are just looking for a quick double up and usually push with a mediocre hand.
